A system for compensating for the oversteer of a motor vehicle includes a controller configured to receive input signals from at least one sensor. The controller may be configured to produce an output signal that is capable of being received by a steering system of the motor vehicle. The input signals typically include a steering pinion gear angle signal, a vehicle velocity signal, and a yaw rate signal. The output signal may be received by a motor that is configured to provide power assist to the steering system in order to maintain the stability of the motor vehicle during an oversteer condition. A method of using the system includes receiving the signals into the controller, producing at least one transmittable output signal to the steering system of the motor vehicle, and articulating at least one steerable wheel in response to the output signal. Receiving the signals into the controller typically includes receiving signals corresponding to a yaw angular velocity actual value and a required yaw angular velocity value signal. Receiving the required yaw angular velocity value signal may include receiving a steering pinion gear angle signal, receiving a motor vehicle velocity signal, and mathematically combining the two signals. The output signal may then be produced by determining the difference between the required yaw angular velocity and the yaw angular actual value signal with respect to time. The articulating of the steerable wheel is typically effectuated through a mechanical manipulation of either the electric power steering system or a variable resistance device.
